VS: Separate compiler and linker PDB files (#11899, #14062)

The MS tools create two types of PDB files as explained here:

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspx

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx

One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file.  Split them up.

In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".

In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically).  Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.

Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files.  Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.

This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.
